Melbourne: Scientists have made an amazing discovery in the form a cave on the Indonesian island of Sumatra that holds a "beautiful and stunning" record of Indian Ocean tsunamis spanning over thousands of years.
Researchers have claimed that the layers of sandy sediments deposited by tsunamis in the cave, south of Banda Aceh, show that tsunamis have variations in time and size, News.com.au reported.
Research team leader, Charles Rubin from the Earth Observatory of Singapore, said that it`s something that communities need to know to develop better policy and planning in the region.
Rubin believes that the layers were dated between 2800 and 3300 years ago and some four to five tsunamis battered the area.
